So did Ikeda sensei explain how he did what he does?
Did he elaborate on "move the inside"?
Were you able to reproduce what he did?
If not, why not?
I woud say, personally, "no" to the first two questions, although some may have understood more of what he was saying than I did.
I don't know whether what I was doing was in any way similar to what Ikeda Sensei was doing, since I can't feel what my uke was feeling, nor what his uke felt, although with at least half of the partners I practised with I could get something of a similar effect. I know I was using too much muscle in most cases, though, and the success of my efforts was not nearly as consistent or reliable as what I was seeing with Ikeda Sensei.
As I mentioned in a previous post, I thought there were some big gaps in Ikeda Sensei's explanations of how he was doing what he did, and most people on the mat at the weekend wouldn't have been able to put the pieces together (even in the longer term) to reproduce his kokyu. All the same, I felt I touched the essence of what he was doing, and know what I need to work on (if not necessarily exactly how to do that!).
